Revision 4056afbcf2d3ee3e9df2788656f3197cc363a2ee authored by Junio C Hamano on 23 February 2012, 05:55:06 UTC, committed by Junio C Hamano on 23 February 2012, 05:55:06 UTC
When falling back to 3-way merge, we run "git apply" to synthesize the fake ancestor tree by parsing the incoming patch, and another "git apply" to apply the patch to the fake ancestor tree. Both invocation need to be aware of the custom -p<num> setting to parse patches that were prepared with non-standard src/dst prefix. Signed-off-by: Junio C Hamano <gitster@pobox.com>

* The given notes_tree 'local_tree' must be the notes_tree referenced by the
* o->local_ref. This is the notes_tree in which the object-level merge is
* performed.
*
* The commits given by the two refs are merged, producing one of the following
* outcomes:
*
* 1. The merge trivially results in an existing commit (e.g. fast-forward or
* already-up-to-date). 'local_tree' is untouched, the SHA1 of the result
* is written into 'result_sha1' and 0 is returned.
* 2. The merge successfully completes, producing a merge commit. local_tree
* contains the updated notes tree, the SHA1 of the resulting commit is
* written into 'result_sha1', and 1 is returned.
* 3. The merge results in conflicts. This is similar to #2 in that the
* partial merge result (i.e. merge result minus the unmerged entries)
* are stored in 'local_tree', and the SHA1 or the resulting commit
* (to be amended when the conflicts have been resolved) is written into
* 'result_sha1'. The unmerged entries are written into the
* .git/NOTES_MERGE_WORKTREE directory with conflict markers.
* -1 is returned.
*
* Both o->local_ref and o->remote_ref must be given (non-NULL), but either ref
* (although not both) may refer to a non-existing notes ref, in which case
* that notes ref is interpreted as an empty notes tree, and the merge
* trivially results in what the other ref points to.

*
* This function will add the (now resolved) notes in .git/NOTES_MERGE_WORKTREE
